PMW3610 Optical Sensor
What is it?
A ready-to-use motion tracking breakout board that's perfect for building custom computer mice, trackballs, or adding motion sensing to any project. It uses the PMW3610 sensor (the energy-efficient cousin of sensors found in gaming mice) with all the tricky electronics already handled.
Documentation & Examples
I built a custom keyboard with integrated trackball, but couldn't find an optical sensor for sale that fit my requirements. I needed support in ZMK, and low energy requirement since my keyboard was wireless. This PMW3610 fit the requirements!
You can use it as a reference when integrating the PMW3610 into your own projects.
